Semrush Keyword Opportunities is a Chrome extension by Tremplin Numérique that highlights keywords on Semrush pages that are missing from the final URL slug of a website.
When you open a keyword report on Semrush, the extension automatically compares each keyword with the corresponding URL slug. Rows are color-coded based on the number of missing words:
- Yellow — 1 keyword missing from the slug
- Orange — 2 keywords missing
- Red — 3 or more keywords missing
This makes it easy to identify pages where the URL could better reflect the target keywords, and prioritize which ones to optimize first.
How It Works
Once installed, the extension runs automatically on any Semrush page. It scans the keyword column and the URL slug column, removes accents for accurate matching, and highlights rows where keywords are missing from the slug. The page updates automatically when you navigate, filter, or paginate within Semrush. No buttons to click, no configuration needed.
Features
- Automatic highlighting — The extension runs as soon as a Semrush page loads and re-runs whenever the content changes. There is nothing to configure.
- Color-coded severity — Yellow for 1 missing keyword, orange for 2, red for 3 or more. You can see your priorities at a glance without reading a single number.
- Accent-insensitive matching — The comparison ignores accented characters so that keywords like « café » and « cafe » are treated as a match. Works across all languages.
- Lightweight and fast — A single content script with no external dependencies. No background process, no popups, no storage, no impact on browser performance.
Who Is It For
- SEO professionals — Quickly audit keyword-to-URL alignment across hundreds of pages without exporting anything to a spreadsheet.
- Content strategists — Identify which pages need URL restructuring or content updates to better match target keywords.
- Agency teams — Run visual keyword audits during client calls directly inside Semrush, no extra tools needed.
- Freelancers — Save hours of manual comparison work on every new SEO audit.
